T 0 (LZZ whom it may concern:

Be it known that 1, Don M. LEMON, a citizen of the United States,resident of Boston, in the county of Suffolk and State of Massachusetts,have made a certain new and useful Invention in Machines for CuttingButter, &c.; and l declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it appertains to make and use the invention, reference beinghad to the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

Figure 1 is a side View of the machine with the carrier in position uponthe table or bed thereof. Figure 2 is a plan view of the same. Fig. 3 isa section on the line 33, Fig. 2. Fig. l is a section on the line %tl,Fig. 2. Fig. 5 is a detail perspective view of the carrier. Fig. (5 is asimilar view of the end rest of the carrier. Fig. '7 is a similar viewof the rest or support for engagement with the bottom of the block ofbutter.

The invention has relation to machines for cutting butter, having forits object the provision of a machine capable of use upon the counterfor quickly and econon'iically separating a large block or tubfnl ofbutter into cakes of convenient size. The machine is equally capable ofuse to cut cheese, bread and similar food substances.

Other objects and advantages will hereinafter appear.

The invention consists in the novel construction and combinations ofparts as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letter a,designates a supporting frame, which may consist of two longitudinalrail or track loars Z), b, braced transversely and having legs L, b, ateach end. Mounted centrally of this frame is a stand 0, having a pan 0,below the frame bars b, I), and carried by this stand are endless loandsaws (Z, (Z, provision for four being shown, these saws being carried bywheels (Z, (Z, having journal bearings in the upper each end formovement upon the rails 6, Z), said platform having a series of rackteeth 7', at one side with which a large spur gear wheel f, havingjournal bearings in the stand 0, has driving connection, through bevelgears j, 7, and pinion 7". This wheel 7, has at its upper end engagementwith a pinion, f, the shaft of which carries a small miter gear 7*, inmesh with a similar gear 5 on one of the saw wheel shafts g, said shaftcarrying a small spur gear or pinion h, having engagement with a trainof pinions la, la, a, upon the shafts of the other saw carrying wheels.Thus upon rotation of the large spur gear f, the table or platform willbe slowly moved along the rails of the stand while the endless saws willat the same time be given a rapid movement.

The table e, is dotted with small knobs or protuberances Z0, Z0, for thepurpose partly of preventing objectionable adherence of butter to thetable. The block of butter being first placed in position upon thetable, it is caused to move by operation of the gearing until the butterhas passed to the opposite side of the saws and been cut into a numberof vcrtical sheets or strips, nine as shown.

Z, is a rest formed of flat bars Z, Z, the channels between said barsbeing open at one end and connected at the opposite end at Z, where therest is provided with inward and upward extending branches m, m. A seatin, is provided at the middle portion of the center bar Z. This rest isnow slid underneath the subdivided block of butter, be tween the knobsZn, 7.1, and av lifting lever it, operated to cause its upturned end a,to engage with this seat m, raising the rest and portion of said stand,and wheels (Z (Z having journal bearings within the pan 0, which isdesigned to contain water or other suitable liquid for cleaning, heatingor moistening the saws in their movement therethrough.

0, is a platform having wheels 0, a, at

the butter thereupon, when the butter and rest are turned upon the leverextension as a center to a position at right angles to the positionformerly occupied, the rest and butter being then let down again uponthe platform. The large spur gear is now turned to reverse the movementof the table or plat form upon the rails of the stand, and the sawsagain passed through the butter, dividing the vertical sheets orsubdivisions into still smaller vertical subdivisions in planes at rightangles to the first cutting planes. The original block of butter is nowsubdivided by vertieal cuts at right angles to each other into verticalblocks, and it is desired to further divide it into horizontal blocks orcakes. To this end a carrier 1', is

provided for the butter, having a skeletonform side portion 2", andparallel horizontal Wires or rods j, having vertical upward extensions jand top horizontal connections f, with the part 2', the channels betweenthe rods of the carrier being open at the inner ends for free passage ofthe saws. For the purpose of holding the block of butter firmly inposition along its vertical walls in the carrier z, a vertical pressurepiece is provided having upper and, lower perforations W, W, engaging ina sliding manner the upper and lower rods j, j, and j j This pressurepiece is thicker andv heavier than the other parts of the carrier andforms the main support therefor, having a lower squared extension ladesigned to closely engage in a sliding, supporting manner a transversesquared groove j, of the table. An adjusting screw 7), having threadedengagement with the part 2", at 2' and rotary bearing in the part 72, at70 is designed upon rotation to n1 ve the carrier 2', upon which thebutter rests until the vertical extensions j j and the pressure pieceis, engage the vertical walls of the butter. block to hold the samesecurely. A horizontal pressure piece 9, has sliding engagement with adepending rod of the part 2", for the purpose of eX erting pressure uponthe top wall of the butter block. The piece q, has horizontal pressurearms passing through slots Q3, Q3, of the pressure piece 70, and isprovided with a set screw 9*, having bearing against the rod to fix theadjustment. The skeleton-form rest Z, is now withdrawn from beneath thesubdivided block of butter, when the carrier 2', is placed endwise overthe butter until the end of the carrier rests upon the table, a rest 0,consisting of parallel rods or vires 0, 0, the channels between the samebeing open at one end as shown at 0 and closed at the opposite ends byconnecting bars 0 being slid underneath the butter between the knobs 7c,7c, of the table into engagement with a slot seat 0 of the bar j at oneend of the carrier. The carrier is now swung at one end thereof upon thetable or platform with the butter resting upon the rods j, j, and 0, 0,until the butter block rests upon its side upon the carrier and thesquared lower end 70*, of the pressure piece 76, rests in its squaredseat or groove j, of the table. The butter is next moved into engagementwith the subdividing saws or wires to make the horizontal cuts, whichare made however by vertical saws. These horizontal cuts are desired tobe thinner or less far apart than the vertical cuts and it is for thisreason that the carrier 2', is made capable of adjustment transverselyof the table.

The upper and lower saw carrying wheels are preferably grooved and theupper wheels are provided withv small radial teeth 8, s,

having engagement with small perforations s, s, of the band saws torender more cer tain the movement of such saws with the wheels. One setof said carrying wheels, preferably the upper set, is provided withsmall auxiliary wheels 6, t, which run in the grooves thereof and areprovided with radial recesses 25, t, for the reception of the teeth .9,s, after they have passed through the perforations of the band saws forfurther assurance against escape of the band. saws from the carryingwheels.

To avoid perforation of the walls of the pan carrying the cleaningliquid for the saws, the shafts of the lower saw carrying wheels (Z (F,are journaled in depending brackets 11, it, having support from theupper edges of the pan.

The band saws have preferably a wavelike serpentine cutting edge, asshown.

Wires may be substituted for the band saws or saws may be used (notshown) and the movement of the saws may be reci rocatory if desired,without departing from the spirit of my invention.

The carrier 2', is shown as adapted for use with a rectangular prismaticblock of butter made from the usual frusto-conical tubful or block bycutting off the tapering edge portions thereof.

The saws may be cleaned or heated by the use of a flame if. desired, themeans for proving which are not shown.
